Background of the issue:
I am trying to resolve an issue with the WPML plugin where I receive error messages related to wpml-sticky-links.php. I have to deactivate all plugins to access WordPress.
Symptoms:
Error messages include: 'Deprecated: Automatic conversion of false to array is deprecated in /home/customer/www/studiobcanada.com/public_html/wp-content/plugins/wpml-sticky-links-old/classes/class-wpml-sticky-links.php on line 19' and 'Warning: Cannot modify header information - headers already sent by (output started at /home/customer/www/studiobcanada.com/public_html/wp-content/plugins/wpml-sticky-links-old/classes/class-wpml-sticky-links.php:19) in /home/customer/www/studiobcanada.com/public_html/wp-includes/pluggable.php on line 1435'.
Questions:
What needs to be done to fix this?
How can I prevent having to deactivate all plugins to access WordPress?
